PVM (Parallel Virtual Machine) is a portable message-passing programming system, designed to link separate host machines to form a ``virtual machine'' which is a single, manageable computing resource. The virtual machine can be composed of hosts of varying types, in physically remote locations. PVM applications can be composed of any number of separate processes, or components, written in a mixture of C, C++ and Fortran. The system is portable to a wide variety of architectures, including workstations, multiprocessors, supercomputers and PCs.
Schedule::Cron is a Perl module that provides a simple but complete cron-like scheduler. It can be used for periodically executing Perl subroutines. The philosophy behind Schedule::Cron is to call subroutines periodically from within one single Perl program instead of letting cron trigger several (possibly different) Perl scripts. Everything under one roof. Furthermore, Schedule::Cron provides a mechanism to create crontab entries dynamically, which isn't that easy with cron. It knows about all extensions (at least all extensions the author is aware of, i.e those of "Vixie" cron) for crontab entries like ranges including 'steps', specification of month and days of the week by name, or coexistence of lists and ranges in the same field. It even supports a bit more (like lists and ranges with symbolic names). It has existed since 1999 on CPAN and is successfully used in many projects.
DB2 is a database management system that offers industry leading performance, scalability, and reliability on your choice of platform from Linux to z/OS. Its Web Control Center offers administrators an easy-to-use interface for maintaining databases, and can be run from any Java-enabled Web browser. For Java developers, DB2 UDB for Linux offers support for JDBC and SQLJ, and Net.Data allows for the creation of dynamic data diven Web applications. DB2 UDB for Linux allows you to harness the power of user-defined types and functions and support for Binary Large Objects.
CMake is a cross-platform, open-source build system. It is used to control the software compilation process using simple platform and compiler independent configuration files. It generates native makefiles and workspaces that can be used in the compiler environment of your choice. CMake is quite sophisticated: it is possible to support complex environments requiring system configuration, pre-processor generation, and code generation.
SendIP is a command-line tool to send arbitrary IP packets. It has a large number of options to specify the content of every header of a RIP, RIPng, BGP, TCP, UDP, ICMP, or raw IPv4/IPv6 packet. It also allows any data to be added to the packet. Checksums can be calculated automatically, but if you wish to send out wrong checksums, that is supported too.
PyMQI is a Python library for working with WebSphere MQ (formerly known as MQSeries) implementing MQI and PCF protocols. It allows one to connect to queues, put, browse, get messages, and to programmatically administer MQ objects. PyMQI has been used in production environments for several years and is known to work on Linux, Windows, Solaris, AIX, and HP-UX with queue managers running on Linux, Windows, Solarix, AIX, HP-UX, and z/OS mainframe.
Exscript is a scripting language for automating network connections over protocols such as Telnet or SSH. It is in some ways comparable to Expect, but has some unique features that make it a lot easier to use and understand for non-developers. It supports parallelization, logging, authentication mechanisms, and a lot more.
PHFTP (PHP HTTP FTP) is a simple and fast Web FTP application. You can upload, download and administer files on FTP servers without a local FTP client, even if you are behind firewalls and proxies. The only thing you need is a Web browser HTTP(S) connection. If you can browse the Internet at your workplace, you can now also establish a FTP connection to any FTP server your PHFTP installation server can connect to.
